1 Introduction Congratulations on your purchase of the Zoom OMAP-L138. This Zoom Development Kit provides a product-ready hardware and software platform for evaluating the functionality of the Texas Instruments OMAP-L138 processor and the Logic System on Module (SOM). 1.1 Scope of Document This QuickStart Guide will list the contents of the, point out the features of the major components, and provide the instructions necessary to verify your development kit is in working order. Any additional usage instructions or details fall outside the scope of this document. Additional resources will be listed at the conclusion of this QuickStart Guide. 1.2 Zoom OMAP-L138 Contents Boards +OMAP-L138 SOM-M1 +Application baseboard Cables and Accessories +5 volt power supply with power adapters for the US, UK, Japan, and Europe +USB A to mini-b cable 4 QuickStart Guide
1.3 Unpack the System Once you have verified that all the development kit items are present, carefully remove the boards from their protective anti-static bags. Check the boards for any visible damage and ensure that there are no broken, damaged, or missing parts. Note: Avoid touching the MOS devices. Static discharge can and will damage these devices.

Align the SOM-M1 over the three board-to-board (BTB) socket connectors in the center of the baseboard (there is an outline of the SOM-M1 on the baseboard silkscreen to show proper placement). See Figure 2.1. 8 QuickStart Guide
Figure 2.1 Align the SOM-M1 over the Baseboard 2. Press straight down on the SOM-M1, applying even pressure over the baseboard BTB socket connectors. See Figure 2.2. Figure 2.2 Connect the SOM-M1 to the Baseboard QuickStart Guide 9
3. Visually verify that the BTB socket connectors on the SOM-M1 and baseboard have mated correctly. To remove the SOM-M1, pull up on the board above the socket connectors. Attempt to pull straight up and refrain from flexing the printed circuit board (PCB) to avoid damaging the SOM-M1. 2.3 Connect to PC In order to communicate with the OMAP-L138 SOM-M1, the needs to be connected to a PC. There are two methods for this: via a null-modem serial cable to access the U-Boot and Linux kernel in SPI flash or via a USB cable to access the processor using Code Composer Studio. The following sections will walk you through each method. 2.3.1 Connect via Null-Modem Serial Cable 1. Connect a null-modem serial cable (not supplied in the kit) to the serial port connector on the baseboard and to an empty COM port on the your PC. See Figure 2.3. Figure 2.3 Connect the Null-Modem Serial Cable to Baseboard 2. Connect the regulated 5V power supply to the appropriate power adapter for the region in which you are using the. 10 QuickStart Guide
Figure 2.4 Connect Power Supply and Adapter 3. Plug the power adapter into an electrical outlet and the 5V line output connector into the power-in connector on the baseboard. Figure 2.5 Connect Power to the Baseboard 4. Before powering on your kit, you will have to verify the baseboard DIP switches are in the correct positions. Please proceed to Section 2.4 for details. 2.3.2 Connect via USB A to mini-b Cable 1. Connect the USB A to mini-b cable (supplied in the kit) to the emulation USB mini-b port on the baseboard and to a USB port on your PC. See Figure 2.6. QuickStart Guide 11
Figure 2.6 Connect the USB A to mini-b Cable to Baseboard 2. Connect the regulated 5V power supply to the appropriate power adapter for the region in which you are using the development kit. Figure 2.7 Connect Power Supply and Adapter 3. Plug the power adapter into an electrical outlet and the 5V line output connector into the power-in connector on the baseboard. 12 QuickStart Guide
Figure 2.8 Connect Power to the Baseboard 4. Before powering on your kit, you will have to verify the baseboard DIP switches are in the correct positions. Please proceed to the next section for details. 2.4 Baseboard DIP Switches There are the two 8-position DIP switches located on the application baseboard at reference designators S2 and S7. By default, all of the switches are set to the OFF position and should remain in that position when completing the steps in this QuickStart Guide. Figure 2.9 DIP Switch Settings ON 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8 OFF S2 S7 QuickStart Guide 13
The S2 DIP switch is reserved for user application general purpose. The S7 DIP switch controls the processor s boot mode and several FET muxes on the baseboard. Table 2.10 describes the function of each switch. Table 2.10 S7 DIP Switch Functions Switch OFF Position ON Position S7:1* Baseboard LCD drive enabled. Baseboard LCD drive disabled.

A default boot mode has been defined by pulling all boot pins (BOOT[0:7]) to a default state on the SOM. The default boot mode is SPI1 Flash; for the purpose of this QuickStart Guide, leave the boot mode set to SPI1 Flash. All available boot modes are described in Table 2.11; however, the use of these boot modes fall outside the scope of this document.

The terminal emulation 14 QuickStart Guide
program must support binary transfers in order to download software to the kit. Although Logic does not support any particular terminal emulation program, we suggest using Tera Term Pro for Windows 2000 or XP (Tera Term Pro is not available for Linux users). Tera Term Pro can be downloaded for free from Logic s website. To install Tera Term: 1. Download the.zip file from Logic s website and unzip the contents: http://support.logicpd.com/downloads/240/ 2. After unzipping the contents, locate the setup.exe file and double-click it. 3. Follow the on-screen instructions to install Tera Term. Once the terminal emulation program has been installed on your PC, open a new serial port connection using the COM port where the null-modem serial cable is connected to the host PC. Set the baud-rate to 115200, data to 8-bit, parity to none, stop to 1-bit, and flow control to none. (Hint: In Tera Term, you can save these serial port settings by selecting Setup -> Save setup... from the file menu. After saving, these serial port settings will be in place every time you launch the Tera Term application.) Figure 2.12 Tera Term: Serial Port Set-up Window 2.6 Get to the Linux Kernel or a U-Boot Prompt The U-Boot bootloader, Linux kernel, and file system are burned to flash memory (SPI1) during manufacture and provide the necessary commands to interact with the OMAP-L138 SOM-M1 and boot into an operating system. QuickStart Guide 15
1. Make sure the development kit is set-up as described in the "Connect to PC" Section and the boot mode is set to SPI1 as explained in the "Baseboard DIP Switches" Section. 2. Start the terminal program you installed on your PC in the "Terminal Emulation Installation" Section. 3. Verify that the serial port settings are correct. See Figure 2.12. 4. Move the POWER ON/OFF switch to the ON position to boot the development kit. Figure 2.13 Switch Power On 5. In your PC s terminal emulation program, you should see U-Boot launch. If you press any key before 3 seconds elapse, you will receive a U-Boot > prompt to modify the boot settings. Otherwise, after 3 seconds elapse from power on, U-Boot will launch the Linux kernel, culminating with a login prompt that will allow you to log in as root (no password). 6. You are now ready to work with the OMAP-L138 SOM-M1 using the Linux kernel or U-Boot. Note: The OMAP-L138 SOM-M1 can also use Code Composer Studio to load board support library (BSL) sample programs and interact with the DSP core on the processor. To use Code Composer Studio with the OMAP-L138 SOM-M1, the EVM must be connected to the PC using the USB A to mini-b cable, as described in Section 2.3.2, instead of the null-modem serial cable. Additional instructions are available in the Zoom OMAP-L138 Development Kit User Manual (http://support.logicpd.com/downloads/1214/). 16 QuickStart Guide
